You're right that the GTX 660 is an energy efficient card and your power supply is just enough to supply them both. However whenever playing demanding games, that utilize SLI, it would put your PSU under constant strain. 550W just doesn't leave enough head room and it may end up shorterning the life span of your PSU considerably. But I guess that does mean that at least you don't have to worry about replacing your 550W for a 750W, until your 550W dies.

Didn't you just buy the computer? You don't want two slower cards in SLI/CrossFire rather than one faster card. If the GeForce GTX 660 isn't fast enough for you, then return it and get a Radeon HD 7970 GHz Edition instead.

Or even a 7950 with the bios flashed to the GHz Firmware is pretty dammed nice and will run allmost anything on ultra on a solid 60fps @1080p.

Hmmm... Now that is true. If I had the money to buy 2 GTX 660s, then I would have got a GTX 670 instead.
